223432-85-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223432-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,4,3 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 223432-85:
(8*2)+(7*2)+(6*3)+(5*4)+(4*3)+(3*2)+(2*8)+(1*5)=107
107 % 10 = 7
So 223432-85-7 is a valid CAS Registry Number.

, p. 249 - 255 (2007/10/03)
1,2-Dihydropyrrolo[1,2-c]pyrimidin-1-ones 2 have been synthesised from pyrrole. We have developed a versatile procedure for the introduction of substituents into the pyrrolopyrimidinones 2, at positions 5 or 7 as desired, and as required by our plans for
